Peeling paint shortens the lifespan of the product and causes many issues, such as increasing the cost burden of repainting.
There are various causes for paint peeling, but the main ones are as follows: 1. Surface Preparation - "Insufficient surface preparation" → Impurities such as oxidation films, rust, and old paint have not been completely removed. - "Residual grease and dirt" - "Improper substrate adjustment" → Appropriate substrate adjustment has not been performed according to the type and condition of the metal. 2. Environmental Conditions - "Salt damage" → In environments with high salt content, such as coastal areas or industrial zones, the paint film suffers from salt damage, leading to accelerated deterioration. - "Ultraviolet rays" → Ultraviolet rays promote the degradation of paint, causing chalking, cracking, and ultimately peeling. - "Temperature changes" → Expansion and contraction of the paint film and substrate due to temperature changes can lead to cracking and peeling. 3. Incorrect Paint Selection - "Weather resistance" → Paint suitable for outdoor or indoor use, as well as heat resistance, has not been selected according to the usage environment. - "Compatibility of paints" → When applying different types of paint in layers, compatibility with each other has not been considered. - "Compatibility with materials" → Paint suitable for materials such as wood, iron, and stainless steel has not been used. 4. Poor Application - "Insufficient drying" → Moving on to the next step before the paint is completely dry weakens the paint film. - "Excess or insufficient application amount" - "Layering interval" → The timing for applying additional layers is either too early or too late.

basic information
"Specific Measures to Prevent Paint Peeling" To prevent paint peeling, the following measures are effective: 1. Thorough Surface Preparation Surface preparation is considered one of the most important steps in the painting process. The most effective method of surface preparation is blasting. Blasting removes all impurities attached to the surface and creates fine irregularities, significantly improving the adhesion of the paint and preventing peeling. 2. Appropriate Selection of Paint It is necessary to choose a paint that has good adhesion to the material of the object being painted. Additionally, consider the environment in which it will be used and the expected lifespan to determine and select the optimal painting system. 3. Proper Painting Work If the paint film is too thick due to not adhering to the appropriate application amount, it can lead to cracking and early peeling; if it is too thin, it can result in inadequate performance. It is essential to adhere to curing times and intervals between coats, and to paint carefully to ensure uniform film thickness. 4. Regular Inspections Paint deteriorates daily due to factors such as ultraviolet rays. Regular inspections of the painted surface can help detect deterioration early and allow for appropriate measures to be taken. If you are concerned about improving the durability and maintaining the appearance of metal products, please consult Harada Ironworks.
